Application January 21, 1933, Serial No. 652,802

Claims. (Cl. 229-55) This invention relates to an improved article ofmanufacture, and the methodof making the same from any appropriate sheetmaterial, such as paper.

A principal feature being to build up a container structure with the aidof shapers or mandrels, from pieces of a pre-formed and scored sheetblank, appropriately divided into relative component parts forconjunctive assembly to form the bodies and covers of containers able towithstand a maximum service and o f such lowcost to encourage its usefor heavy duty in an article of this type. l

A principal object'of the present invention is to provide a completesubstantially fluid-proof container, including a body portion` and acover, each having means, in the walls thereof, for effectivelyreinforcing the structure to withstand the destructive action of fluidsor other contents for an unusual length of time. v

A further object is to provide a method for making reinforced containersfor many purposes,

including drinking cups, from pre-cut parts of a single rectangularsheet of material with absolutely no waste pieces of material remaining,thus resulting in high economy and super-strength in an article of thelaminar type.`

- Suitable means, such as a powerful fluid-proof adhesive, may beemployed'to unite the builtup parts in forming the container, drinkingcup or the like; the adhesive being applied to advantageous or desirableareas on the several portions of a sheet blank at the time the cuttingis done to prepare the parts for use, if desired, or said ad- -hesivemay be applied to an entire face of each of said parts or t0 an entireface of the said sheet blank, before the cutting operation.

For the sake of simplicity, there is shown and described a container ofrounded or cylindrical conformation, in cross section, but, of course,various cross-sectional or general shapes may be adopted and nolimitation is intended by the phraseology of the above statements ofinvention or in the following description in detail, with reference tothe drawings, illustrating one form of the invention, which show thecontainer as having vertical parallel side walls, but said container maybe formed with flaring walls (not shown) to provide a drinking cup orother useful article of that general shape, or other practical shapes.

In the drawings illustrating one preferred form of our invention, Fig. 1is a partial sectional side elevation of a container constructedaccording to what we now believe to be a good form of our invention, thewalls being broken away to better disclose theconjoining of the partsbut in exagerated relative dimensions.

Fig. 2 is a partial horizontal section on broken line 2--2 of Fig. 1.

Fig. 3 is a horizontal section taken on the broken line 3-3 of Fig. 1.

Fig. 4 is a partial horizontal section, taken on the broken line 4-4 ofFig. l.

Fig. 5 is a fragmentary View taken on the line 10 5-5 of Fig. 1.

Fig. 6 is a face view of a paper or other sheet blank divided intopieces o1'. portions providing the material from which the improvedcontainer is constructed by a method lof sequential step operations.

Figs. 7, 8, and 9 are diagrammatic views showing, respectively, the rst,second and third operative steps in the method of forming a container ofthe type described. go

Fig. 4l() is a fragmentary section showing an additional disk-piecebetween ythe layers 2| and 2 Ia, of the bottom to reinforce the same.

Referring now to the drawings in detail, the improved container body I0,as in Fig. 1, comprises a cross-sectionally cylindrical side wall II, abottom I2, and a separate removable cover I3, having atop I3a; the coverbeing of a size to fit snugly around and over the mouth or open end I4,of the container.

Our method of building the improved container I0 consists in firstsupplying a sheet blank (Fig. 6) of proper size and contour so thatno'stock waste remains. This sheet blank I5, being divided or cut as atI6, into pieces or portionsgl! to be assembled and united as hereinafterset forth:

In 4carrying out the invention, one face of the sheet blank may beentirely coated with a suitable adhesive as at I8,`or the edges only ofthe pieces or portions I1, may have applied thereto lines of adhesive,as at I9.

In thelpresent form, the identical portions 20, 20a and 20h maycomprise, collectively, the laminated 3 ply side Wall II of thecontainer shown in Figs. 1 to 5 inclusive, and the identical parts 2|and 2 Ia, collectively may comprise the laminated 2 ply bottom I2 ofthesaid container. V

The identical portions or pieces22, -22a and 22h of the sheet blank I5may comprise in a general sense, the side wallV I 3b of the cover I3 ofthe container, and the identical parts or portions 23 and 23a of thesheet blank I5, may collectivelycomprise the top I3a of the cover I3, ashereinafter described.

the

The circular bending lines of the bottom poritons 2l and 2 la, and thetop of the cover portions 23 and 23a, are indicated at 25 on the sheetblank I5, 'and outward ofv these circular bending lines are short andlonger reinforcing portions 26 and 21, which, in the assemblingoperation, areturned inwardly between the respective side walls of thecontainer body and its cover to reinforce the corners, and the sidewalls for some distance from said corners, as clearly shown in Figs. 1and 5 of the drawings.

By referring to Figs. 1 and 3 of the drawings, it will be seen that theshort and longer reinforcing portions 26, 21 of the top and bottom partsyor layers, are placed in diametrically staggered relation, to lie ateight diametrically opposite points in the side walls, so that thereinforcement of said walls is extended further at eight equally spacedareas, and of course the shapel and size of these longer reinforcingextensions may be varied if desired or required, or the reinforcementsin the walls of the container and its cover may be of other forms.

The blank pieces for forming the bottom and top layers of the containerare here shown as squares of sheet material, the corners of vsaidsquares and the narrower portions therebetween being turned upwardly orinwardly between the side walls toI serve as the reinforcing extensionsvof said top and bottom pieces of the blank I5,

as will be evident.

Suitable mandrels or forms 30 and 3| may be supplied, on which the wallportions 22, 22a and 22h and 20, 20a and 20h may be rolled alternatelywith respect to.` the application and bending the reinforcing portionsof the top layers 23 and 23a' and the bottom layers 2l and 2la inwardlyand against the side of each progressive wall portion or layer to bepermanently interposed in the wall structures, as best shown in Fig. 1,of the drawings. g

Briefly, with reference to Fig. 6, a body wall piece 2Gb, is rolledaround the mandrel 3l; its

vends overlapping and sealed as at 24 in Fig. 2,

after which, a square bottom piece 2|a is placed in proper position onthe cylinder thus pro-duced and is engaged by a suitable cupped die 3m,which turns the reinforcing portions 26-21 inwardly or upwardly intocontact with the outer lower Wall portions of they portion or piece 2Gb;a second wall piece 20a is then applied, rolled and sealed over the lastdescribed pieces, after which, a second bottom piece 2l, is applied bythe cupped die Sla, and finally another wall piece 20 is rolled andsealed over the laminated wall and bottom described, thus providing a 3ply wall and a 2 ply bottom in a container, and

finally this structure may be hard pressed, with or without heat, makinga hard, rigid body portion which will stand up yunder long hard service.

The cover I3 for the container body I0 is con- 5 structed in the samemanner by using the mandrel 30 and a cupped die SIb, see Fig. 7.

Of course it will be understood that for high speed production, powerdriven means or mechanism may be employed for assembling, shaping 10 anduniting theccmponent parts of the laminar container and its cover, abovedescribed, and as shown in the accompanying drawings.

In the claims, the body and cover collectively will be termed container,unless otherwise l5 designated, and since the body and cover areconstructed by the same method, a claim for forming the body only willbe submitted.

In Fig. 10, of the drawings there is shown a disk-piece 5D, placedbetween the bottom layers 20 2| and 2 la to reinforce the same, ifrequired, and a similar disk-piece may also be located between thelayers 23 and 23a for the purpose set forth.

What we claim isz- I 1. A container comprising side and end walls 25 ofmultiple sheet paper, the sheets of the side walls being one greater innumber than the end walls; the sheets of the end walls having triangularreinforcing extensions interposed respectively between the inner sheetand the next our sheet 30 of the side wall and between the next outersheet and outer sheet of the side wall of the structure, saidreinforcing extensions being permanently fixed in cross wall staggeredrelation and in circumferential equidistant positions between said 35sheets.

2. A container comprising laminated side and end walls; the lamin of theend walls each having four corner extensions interposed between therespective center and side lamin of the side walls 40 in alternatecross-wall and annular staggered relation to add strength to the saidside wall.

3. A container comprising an odd number of side wall layers and an evennumber of end wall layers of sheet material; the end wall layers havi5ing prolonged corner portions interposed respectively in staggeredrelation between the side wall layers of the container at opposite sidesof the center layer and within the other layers of said wall. 50

4. A container comprising a side wall of layers and end walls of layers,each layer of the end walls being provided with four diametricallyopposite reinforcing corner portions extending from the end walls andinterposed between the side 55 wall layers of the container inrespective staggered relation at opposite sides of the central layer ofsaid side wall. I

5. A container comprising a laminar side wall of three layers andlaminar end walls of two 60 layers, the layers of the end walls beingprovided with corner portion extensions interposed between the layers ofthe side wall in respective annular and cross-wall staggered relations.
